Slotted Metal Tubes - China

Slotted metal tubes are fabricated from perforated sheets with slot holes/openings punched with the pre-made dies or models.

Then the sheets are welded to form a cylinder or pipe.

The pattern of the opening is determined by the shape of the die.

In perforating and slotting, die making accounts greatly.

Hengda has first-class digital controlled CNC punching press and an extensive range of dies to provide stainless steel and aluminum slotted perforated tubing with high opening precisions.

Punching Dies:

The die for punching slotted pipe can vary in the width, length, patterns to meet customers’ requirements.

The ends of the slot can be round or square or custom made.

Metal Materials:

The materials most frequently used to production these metal pipes and tubes are stainless steel AISI 304-316, stainless steel, aluminium alloy and any other material suitable for perforation and slotting.

About the Slotted Hole Patterns:

Slotted Holes are elongated holes with round or square ends.

They are available from stock in either a side staggered or a straight line pattern in plain steel.

Others gauges, hole sizes, patterns and materials are available by special order.

Punched sheets and pipes offer more flexibility and rigidity to arrange store display, giving a fresh and elegant look with flexibility in quality.

  Specificatio n
  
  Thickness verifying from 0.35mm to 3 mm and width maximum 1200mm.
  
  Standard sheet size is 1000mm*2000mm.
  
  and 1000mm*2500mm.
  
  Custom order acceptable.
  
  Specify the following when you order:
  
  
  
  A.
  
  Specify the hole shape for perforated metal products:
  
  Round, square, long round, triangle, scale, diamond, oval, hexangular, slot etc.
  
  
  
  B.
  
  Sheet Metal Aperture
  
  The minimum diameter we can fabricate is 0.8mm to 4 mm thickness.
  
  C.
  
  Perforated Pattern
  
  Whether it is rRound, square, oblong, triangle, slot, hex, oval, diamond and a broad variety of special shaped holes.
  
  
  
  D.
  
  Pitch
  
  Hole center is the distance from the center of one hole to the center of the nearest hole in the next adjoining row.
  
  
  
  
  
  E.
  
  Open area
  
  When you order, please keep in mind that punching holes in a material add stresses that can result in distortion of the product.
  
  The higher the open area, the more material distortion takes place, especially when the perforated pattern is bordered by margins on all four sides.
  
  But these distortions can be removed by our special in house leveling process.
  
  
  
  
  
  F.
  
  Metal Margins
  
  Margins are the blank area along the edges of the sheet.
  
  You should provide the width of each margin on all four sides (measured from the edge of the sheet to the edge of the first hole).
  
  
  
  G.
  
  Tolerances on thickness, pitch, openings, flatness, and shearing for perforated products.
  
  You should specify a specific tolerance , so we can give you a precise product.
  
  Standard tolerance will be made unless you specify.
